Abstract
The utility model discloses a long-life universal joint with inhale gasket that shakes mainly includes the cross, and four bearing overcoat of cross are equipped with the axle sleeve, are provided with the round kingpin between the axle sleeve and the axle journal of bearing, it shakes the gasket to shake to set up between kingpin and the axle sleeve, it is porous structure to shake the gasket, and equidistant crisscross a plurality of apertures that are provided with in the gasket that shakes. The utility model discloses under the condition that does not change transmission shaft overall structure, through the structure of improving bearing gasket in the universal joint, with bearing gasket design for porous structure, increase gasket oil storage ability, make the bearing gasket play a buffer spring's effect simultaneously, can absorb the transmission shaft under high-speed, the wide-angle operating mode the cross axle to the energy that the axial impact force of bearing brought, reduce the damage that the impact brought, improve universal joint life.
Description
Technical Field
The utility model relates to a field of car universal joint, concretely relates to long-life universal joint with inhale the gasket that shakes.
Background
The universal joint has the function of transmitting torque and motion and is the 'joint' part of the transmission shaft. When the transmission shaft rotates to transmit torque and motion, the bearing of the universal joint rotates circumferentially around the universal joint cross shaft journal to realize variable-angle power transmission. However, when the installation angle (working pivot angle) of the transmission shaft is large and the rotating speed is high, the universal joint bearing not only rotates around the universal joint cross axle journal but also has relative sliding in the axial direction of the cross axle journal, at the moment, the end part of the cross axle journal can generate periodic impact force on the bearing, meanwhile, a mutual sliding shearing friction force exists between the cross axle journal and the needle roller, and vibration can be generated in severe cases. The vibration of the traditional universal joint is intensified under the working conditions of high speed and large angle of the transmission shaft, the abrasion is serious, the service life is short, and the comfort is poor.
The end part of the journal of the existing universal joint and the bottom of the bearing store oil in the form of a solid gasket and buffer the impact vibration of the cross shaft and the bottom of the bearing, and the design scheme ensures that the oil storage capacity and the vibration reduction effect of the gasket are extremely limited, so that the service life of the universal joint under the working conditions of high speed and large angle cannot be prolonged.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a long-life universal joint with inhale the gasket that shakes.
The purpose of the utility model is accomplished through following technical scheme: the long-life universal joint with the vibration absorption gaskets mainly comprises a cross shaft, a shaft sleeve is sleeved outside four bearings of the cross shaft, a circle of roller pin is arranged between the shaft sleeve and a shaft neck of each bearing, the vibration absorption gaskets are arranged between the roller pin and the shaft sleeve and are of a porous structure, and a plurality of small holes are formed in the vibration absorption gaskets in an equidistant and staggered mode.
The utility model has the advantages that: the setting of porous gasket can greatly increase the oil storage area, fully absorb the axial impact energy of cross to the bearing, cushion the impact of cross to the bearing, furthest reduces the damage that the cross strikes to the bearing, improves bearing lubrication performance to improve the life and the whole car travelling comfort of universal joint.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partially enlarged schematic view of the vibration absorbing gasket.
Description of reference numerals: the device comprises a cross shaft 1, a roller pin 2, a vibration absorption gasket 3, a shaft sleeve 4 and a bearing 5.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawings, the long-life universal joint with the vibration absorption gaskets mainly comprises a cross shaft 1, a shaft sleeve 4 is sleeved outside four bearings 5 of the cross shaft 1, a circle of roller pin 2 is arranged between the shaft sleeve 4 and a shaft neck of each bearing 5, the vibration absorption gaskets 3 are arranged between the roller pin 2 and the shaft sleeve 4, the vibration absorption gaskets 3 are of a porous structure, a plurality of small holes are formed in the vibration absorption gaskets 3 in an equidistant and staggered mode, the number and the size of the holes are determined according to specific working conditions and structures, the gaskets of the porous structure can absorb the impact energy of the cross shaft on the bearings and play a role in buffering, in addition, the vibration absorption gaskets 3 can be manufactured by adopting 3D printing, and energy and materials are saved more.
The utility model discloses under the condition that does not change transmission shaft overall structure, through the structure of improving bearing gasket in the universal joint, with bearing gasket design for porous structure, increase gasket oil storage ability, make the bearing gasket play a buffer spring's effect simultaneously, can absorb the transmission shaft under high-speed, the wide-angle operating mode the cross axle to the energy that the axial impact force of bearing brought, reduce the damage that the impact brought, improve universal joint life.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
